ocmterso, 194s, serial Ne. 5752s' 3 Claims.

This inventionv relates to a metal window screen for application toWindows and doors, whereinl the frame is formed of sheet metal in whichthe screen mesh is interlocked with male and female formations providedin the metal frame, this being a substitute of their abandonedapplication Serial No. 714,368, filed December 6, 1946.

A feature of the invention resides in the corner structure for retainingthe corner abutments of the side and end frame members securely lockedand reinforced.

Thus, the invention resides in forming the frame members of the screenfrom sheet metal strips, each of which is folded longitudinally to theedges of the screen mesh. The screen mesh-` is then interlocked to befirmly secured and stretched within the frame members by stamping orrolling a longitudinally extending bead,

such as to form an interlocking offset by which the wire mesh isstretched and secured.

More particularly, however,` the' ends of each of the frame members aremounted to abut each other at the respective corners to be secured bycorner gussets of sheet metal to which the members are locked againstlongitudinal displacement by a break in thebead formation, ashereinafter more fully set forth and described, it being understood thatchanges, modiiications and variations in the structure as hereinspecifically disclosed, may be resorted to as falling within the scopeof the invention as claimed.

The full nature oi the invention will be understood from theaccompanying drawings and the following description and claims:

Fig. l is a plan View showing a section of a metal screen structure,with parts broken away.

Fig. 2 is a section taken on the line 2 2 of Fig. l.

Fig. 3 is a section taken on the line 3-3 of Fig. l.

In the drawings there is shown a metal screen applicabl'J for screeningwindows, doors and the like, which includes the wire mesh screen IU,side frame members Il, and end frame members I2. In larger screens itmay be desirable to provide a cross member I3 extending between andsecured to opposite side frame members I l. Each frame member il and endmember I2 has its ends mitered as indicated at M for direct abutment to:provide a rectangular frame of the usual character. The mitered andabutting ends of the side and end members are secured and held togetherby the'v corner gusset plates I5, there being provided one such cornergusset plate I5 at each ofthe four' corners of the usual rectangularframe. Wherein a cross plate I3 may be employed, side gusset plates I6,triangular in shape, maybe employed to interlock and secure theadjoining ends ofthe cross member I3 to the'side members l l,respectively.

The side and end members II, I2 are formed of sheet metal foldedcentrally and longitudinaily to provide the opposed portions Il, I8 withan outer roll I9, such as to form a finishing and reinforcing outeredge. Between the portions I'I, I8 the Wire mesh lll is inserted withits edge lying close to the roll i9. The side and end members are thusarranged to embrace the edges of the' wire mesh, but 'with their miterededges I4 in abutment. In such relative position the corner igussetplates t5' are inserted to lie against one 'side of the wire mesh, oneleg being embraced by the portions lI, I8 of the side member II and the.other leg thereof by said portions of the end member I2. i

With the wire mesh it and the gusset `plates le thus embraced by andbetween the side and end members, the structure is locked in place bydeforming their respective adjacent surfaces through crimping, stamping,rolling and the like. As herein shown with the structure assembled, theside and end members l I, I2 are formed with centrallyandflongitudinally formed beads 2l), 2l running throughout substantiallybut not entirely the full length of the respective members, the bead 2ibeing formed in the portion I8 to nest within the bead 2b formed in theportion Il. In deforming the metal to form said interlocking beads, thewire mesh and a portion of the gusset plates are similarly andcorrespondingly deformed to interlock therewith. Thus, said beads beingformed in the members to extend longitudinally thereof throughoutsubstantially their entire length, act both as reinforcing andstrengthening formations to lend rigidity to the frame members, as wellas provide an interlocking between the members, wire mesh and gussetplates.

However, to interlock said frame members with the gusset plates toprevent displacement thereof longitudinally of the beads 2li, 2 I, saidbeads are terminated short of the abutting ends of the frame members, asindicated at 22, merging into a flat or unbeaded portion indicated at23. Thus, spaced from the beaded portions 20, 2l and separated therefromby the normally flat portion 23, there is provided a short interlockingbead portion 24,

25 adjacent to and running into the respective end members. By reason ofthe shoulder formation at the ends of the beads 20, 2I, as indicated inFig. 2, and the adjacent spaced shoulders formed by the beads 24, 25, asindicated at 26, an interlock with the wire mesh and gusset plates isprovided against longitudinal displacement of the side and end membersrespectively relative thereto.

Wherein a cross member I3 may be employed the gusset I6 is interlocked,together with the wire mesh I9, against lateral or inward displacementby the interlocking beads 20, 2 I, and against longitudinal displacementby the interlocking beads 21 formed centrally and longitudinally of thecross member I3. The cross member I3 is, therefore, preferably formed oftwo strips of sheet metal lying adjacent each other on opposite sides ofthe wire mesh with their ends secured together between the portions I'I,I8 of the side frames I I and their intermediate portions securedtogether by rivets 28.

With the wire mesh extending between the opposed portions I1, I8 of theside and end members, upon forming the bead 2I therein, the wire meshwill be stretched in conforming to the bead so that any sag is removedand the mesh tightened and thereby clamped taut without the necessity orrequirement of extraneous means usually necessary for this purpose.

From the above described structure it will be observed that all of themetal screen, including the frame, may be readily formed with the wiremesh rmly secured and stretched thereby within the frame members and theframe members secured at their corners by interlocking deformationsdeveloped through a mere stamping or rolling operation and Withoutemploying extraneous or other securing means. Furthermore, thedeformations of the side and end members, such as to secure themtogether with the wire mesh, provides a reinforcing medium which alsolends a decorative and finished apearance to the structure.

The invention claimed is:

1. A metal screen for windows, doors and the like comprising side andend frame members of sheet metal folded to U-shaped cross section andhaving mitered abutting ends, a panel of wire mesh having its side andend edges extending into and embraced by the folded portions of saidmembers respectively, interlocking beads formed in said members and wiremesh for gripping and securing said panel therein, corner platesextending into and embraced by the folded portions of said membersadjacent their corner forming ends, and interlocking elongated beadsformed in the respective end portions of said members and said plates toprovide opposed and spaced interlocking end shoulders, whereby relativemovement of said plates and members longitudinally thereof will beprevented.

2. A metal screen for windows. floors and the like, comprising side andend frame members of sheet metal folded to U-shaped cross section andhaving mitered abutting ends, a panel of wire mesh having its side andend edges extending into and embraced by the folded portions of saidmembers respectively, corner plates extending into and embraced by thefolded portions of said members adjacent their corner forming ends, anda series of decorative and reinforcing beads formed longitudinally ofsaid members for gripping and securing said panel and corner platestherein, said beads including spaced end shoulders within the area ofsaid corner plates to prevent relative movement of said plates andmembers longitudinally thereof.

3. A metal screen for Windows, doors and the like, comprising side andend frame members of sheet metal folded to U-shaped cross sectionarranged to provide a frame structure with their respective adjacentends forming corners, a panel of Wire mesh having its side and end edgesextending into and embraced by the folded portions of said membersrespectively, corner plates extending into and embraced by the foldedportions of said members at the corners of said frame structure, and aseries of interlocking deformations formed in said memberslongitudinally thereof, said deformations being spaced from each otherwithin the area of said corner plates for providing opposed and spacedinterlocking shoulders to prevent relative movement of said plates andmembers longitudinally thereof and secure said panel therein.
